T 0 all whom it may concern:

Be it known that l', Andree CAMPBELL, a citizen of the United States, residing in Chicago, in the county of Cool; and State of Illinois, have invented a new and useful Improvement in Gravel Dump Cars, of which the following is a specification.

My invention relates to improvements in dump cars, and more particularly to improvements in dump cars of the kind having the hinged doors in the upright sides of the car, and which are specially designed for gravel cars. a

The object of my invention is to provide an improved and simple, efiicicnt and durable construction of gravel dump car, in

which the doors or hinged sides may be firmly held and locked in their closed position, and also securely and properly held. in their open position, while the gravel is being discharged from the car by the plow in the usual manner, and in which one and the same door fastener or catch will serve to perform both these functions. vMy invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and by which this object or result is accomplished. In the accompanying drawing forming a part of this specification, Figure 1 is a plan view of a gravel dump car embodying my invention, one-half the length of the car being omitted for clearness of illustration. 52 is a side elevation. Fig. 3 is a cross section on line 3-3 of Fig. 1. Fig. 4 is an enlarged detail elevation. Fig. 5 is a detail cross section on line 5--5 of Fig. 4 and Fig. 6 isa view similar to Fig. 5 showing the parts in another position.

In the drawing, 1 represents the car body, 2 the center sills, 3 the upright sides of the car body, 4 the floor or bottom, 5 the stakes or upright frame members of the car body, (5 the imaged doors in the upright sides of the car body, 7 the hinges connecting the doors thereto, 8 the door catches secured by bols 9 to each of the hinged doors near the lower edge thereof. Ez'icu of the catches 8 is furnished with a book 10 adapted to engage the shaft. 11 on the operating lever 12, which is furnished with a head 13 for reception of the shaft, and a wedge or cam acting head 1 for engagement with the cam socket 15 of the bracli'ct itl, which is of the car to the other.

secured to the side sills 17 of the car body. The side stakes 5 of the car bodyare furnished with curved slots 18 to receive the operating shaft 11 of the operating handle, and permit the operating shaft to swing about the fulcrum 19 of the operating lever as a center. When the operating lever is in the position shown in Fig. 5, the operating shaft 11 is locked firmly in engagement with the catch, thus holding the doors closed as 65 the wedging or cam acting head 14 at this time wedgingly engages at the point or per tion 20 with the wedging cam acting socket 15 of the bracket 16. And when the operating handle or lever 12 is turned into the position shown in Fig. 6, the wedging or cam acting head l iengages the portion .21 of the socket 15, and thus holds the operating lever securely in this position so that the shaft 11 cannot engage the hoolt of the door catch or fastener.

Each of the upright sides of the car is provided with a series of hinged doors 6, lbcated between the upright stakes, so that practically thewhole side of the car may be ope ed out for the discharge of the gravel as the discharging plow moves from one end A common \operating shaft 11 is employed for all the doors on one side of the car, and each door is prefen ably furnished with two door catches or fasteners 8, one near each end edge of the door. By reason of the wedging or cam construction or shape of the head 14 and its coiiperating cam socket 15,the operating shaft is located and securely held in either its lowermost, position for holding the doors closed or in its uppermost position when the doors. are openbr unfastened. At or near each end of the operating shaft, the lever 12, carrying the heads 13 and 14 is provided with a handle 23, by means of which the operator raises or lowers the operatilw shaft as required. The intermediate operating levers 12 are not provided with a handle 23.

I claim 1. In a. dump or gravel car, the combination witha car body having uprightisifdes furnished with a series of door openings, of doors hinged at the upper edges for closing said openings, door catches secured thereto, and having hooks, a movable door. locking shaft, and a lever for raising and lowering said shaft having a cam or wedge acting head and a cam socket on the car body for iassr AVAILABTLE coPY engagement with said head, substantially as specified.

2. In a dump ear, the combination with a car body having side stakes furnished with slots, doors hinged at their upper edges and closing openings in the upright sides of the car body, door catches secured to the doors, a common locking shatt extending through said slots in the car stakes and adapted to engage the door catches, operating levers for raising and lowering" said shaft provided with wedge acting heads and cooperating wedge acting); sockets engaging said heads to hold said levers in either their raised or lowered positions, substantially as specified.

3. in a dump car, the combination with a car body having side stakes furnished with slots, doors hinged at their upper edgesand clos ,e" openings in the upright sides of the car body, door catches secured to the doors, a common locking sha't't extending through said slots in the ear stakes and adapted to engage the door catches, operating levers for raising); and lowering, said shaft provided with wedge acting heads and coiiperat'ing wedge act" sockets engaging said heads to hold said levers in either their aised or lowered positions, said levers at the ends of the car being furnished with handles, substantial y as specified.

In a dump car, the combination with the car body, of hinged loors furnished with 'atches. a locking shaitt adapted to en 'age said catches, a lever for raising and lowering said shalt having a wedge acting head, and a eoi perating wedge acting socket, substantially as specified.

5. In a dump car, the combination with the car body, of hinged doors furnished With catches, a locking shaft adapted to engage said catches, a lever for raising and lowering said sha't't having a wedge acting head, and a cooperating wedge acting socket, said head and socket being adapted to lock and hold said lever in both its raised and lowered positions, substantially as specified.

(5. In a dump car, the con'ibinatigm with the car bodv. ot' hinged doors furnished with catches,a lockingshai't adapted to engage said catches, a lever for raising and lowering said shalt having, a wedge acting head, and a coiiperating wedge acting socket, said head and socket being adapted to lock and hold said lever in both its raised and lowered positions, said car body having side stakes furnished -with slots through which said shaft passes, substantially as specified.
